Abstract
Antenna carotenoids are investigated by photoacoustic spectroscopy in the photosynthetic bacteria Rhodospirillum rubrum and Rhodopseudomonas sphaeroides . Energy storage in these organisms is revealed by the photoacoustic spectra. A simple method is proposed to evaluate the efficiency of energy transfer between carotenoids and bacteriochlorophyll.
